This invention relates to a digital signal reproducing apparatus. This invention is applicable to an apparatus such as a video tape recorder and an optical disk drive, using a Viterbi decoder therein. Noise characteristics are equalized at points of discrimination by adding an equalized signal SPR4 of a differential system and an equalized signal SPR1 of an integrating system in a weighted manner, or by adding up metrics Maa-Mbb, (Ma', Mb') relative to amplitude reference values calculated for the two equalized signals SPR4 and SPR1, over each of relevant paths in a weighted fashion. The arrangements allow the inventive apparatus to avert noise-induced deterioration of discrimination accuracy.

A system and method for detecting whether a video signal is modified by a video-tape-recorder-design based anti-copying process. A proper portion of the video signal is identified and filtered, and potential anti-copying artifacts in the filtered signal are counted by comparing the filtered output against a threshold derived from the video-tape-recorder-design based anti-copying process. By cross-correlating the number of potential anti-copying artifacts, found on multiple scan lines across multiple frames, with an expected minimum range and/or number of anti-copying artifacts derived from the video-tape-recorder-design based anti-copying process, anti-copying modifications of the video signal are detected. In this fashion, traditional video-tape-recorder-design based anti-copying processes are applied to modem digital video recording systems.

Radio waves transmitted from the antenna of a broadcasting station are received by the antenna of a television receiver. The television receiver extracts an EPG from the received radio waves and transmits it to a remote controller via an infrared transmission/reception section. The remote controller displays the received EPG on a LCD and is then rendered in a state of waiting for selection of a program. If some program is selected and then a reserve button is manipulated, the remote controller transmits a control command for a recording reservation to a video tape recorder. The video tape recorder receives the control command with an infrared transmission/reception section, whereby the recording reservation of the designated program is set.

Generally, an existing video surveillance system directly stores real-time information which is monitored through a surveillance camera into a video tape recorder, not only is a video playback period prolonged, but also a large amount of storage space is occupied. According to a studied useful video recognition video tape recorder, an intelligent video surveillance analysis technique is utilized to achieve a goal of automatically starting a video tape recording function only when target video information is collected, an alarm system is simultaneously triggered when the video tape recording function is automatically started according to a set work recognition mode, and disadvantages of a traditional video tape recorder are thoroughly overcome. Meanwhile, the useful video recognition video tape recorder further achieves that useful information can be automatically identified and classified, packed and stored again after the classification and can be simultaneously and piecewise played when replayed, corresponding display frames can be activated and segmented according the number of the segments, a large amount of space is saved for the storage of video information, time for retrieval, playback and query of the useful video information is reduced, and therefore precious time is saved for seizing opportunity to detect a case.

Original video data of a first format is edited. The first format video data has jitter frames (626) inserted therein and is displayed at a first frame rate. The original video data is read from a video tape recorder (301) in the first format and converted into a second format with no jitter frames, displayable at a second display rate. Time-code of the converted video data is related to time-code of the original video data so as to identify frame types for the converted video data. A portion (603-606) of the converted video data is modified to produce modified video data in the second format. New video data is generated in the first format by processing the modified video data. An edit processor is configured to replace an edit portion of the stored original data with the new data by defining an edit range with reference to the new data, selecting an edit field with reference to the frame type so as to initiate an edit on a data boundary. New data is written to the video tape recorder and an edit field is selected again before completing the writing process. In this way, video edits occur at positions that are consistent with data boundaries irrespective of the selected edit position.
